I don't know if this 3.03 is the UBA version, in my case I got this values:

If you have a Moduline 400 instead of the RC35 some datagrams will be different. It is just a tough but, if the hardware of both thermostats are equal, can this datagram difference come from the firmware version installed? I have found that some commands that should work in my module according to ...

Hi Patrick,

As Kees says, I have done some work regarding RC35 controller. I have uploaded some code in this Github project. More documentation can also be found in this blog.

Oups yeah sorry, you are right. There are four different temperatures in the A3 packet: The attenuated temperature (gedämpfte Außentemperatur) which considers the building characteristics Current room temperature. The temperature 1, current external temperature. The temperature 2, temperature 1 d ...

both values are indeed the room temperature. Looks like the last value is the actual temperature. And the first value seems to be a delayed version of the current measured temperature. Is this common bahaviour to send a kind of delayed temperature? Could perhaps also be an averaged temperature ...

Hi bbqkees, I am using your code an your circuit for reading my Buderus EMS-Bus. It works fine, but I have the folowing problem: I want to read some other values then your code provides. There for I used your telegram-tabels for building adress, frametyp, offset and vartype That worked e.g. for ww ...

no i didnt try ur code yet. Yes i can read and write to the bus NEFIT 10 52.6,32.6,41.4,40.9,18.8,19.0,1,1.8,3.05,0.00 and i can switch from night to manual to clock. but the software is a bit buggy. does ur code support the moduline 300? this software is for the moduline 300. As bbqkes pointed out ...

After reading alot for a few days i still have some questions Is this a good shopping list for everything that i would need? No, it is just a good start point. This list was prepared for AVR NetIO, but if you use arduino you should adapt it (and remove the 10 pin sockets and connectors, etc.). How ...

Hi bbqkees, sorry if I gave you grief - my bad :oops: The problem was in a library I included (for connecting an ESP8266 via SPI, which saves a serial port, hopefully aloowing me to use an Arduino pro nano, which has a much smaller footprint than a mega). Problem detected and destroyed :-) Have a ...

Yes Icon, you are totally right. I should have corrected this code in my Arduino but not updated it in Github, sorry for that. I am not using Domoticz currently, but just in case it inspires somebody, this is the web interface that I have developped in order to control the boiler. http://i.imgur.com ...

Hi Icon. Yes, I am preparing a GitHub Project with this code. I hope I will finish it during the weekend. I will post a lik. In this repository I have uploaded my code. https://github.com/danidata/Calduino-WiFly-Arduino-EMS-Buderus It is initially based on bbqkees' Project and uses its NefitSerial ...

Delchrys it is becoming more and more difficult to follow your posts. Anyway, I will try: • Yes, the sending part is needed to get additional data from the EMS Bus. Otherwise you will only get the datagrams automatically sent by your boiler which, if I remember well, were the slow monitors (UBA and U ...

i just like to see which information is available, from there i will decide which i will log to my domoticz setup. It seems that your code gets more info than bbqkees's code. For now I'm not using the TX part. I like to read only. Your code uses Serial3 i presume??? Yes, i use Serial3 to ...

Delchrys, I cannot make a "quick alteration" in my code so it doesn´t use WiFly (385 references...). But you can comment whatever you need. If it stops due to no wifly connection, just comment the wifly initialization (setupWifly();) and make your own loop to read/write the information in the EMS ...

Thank you for your help bbqkees. I finally archieve the write functionality. I did not get to understand why the original author was using 0x91 and 0xA8 as types. As you say, some values are masked by 0x80 but those are only the destination Address and the dataoffset requested, not the frame type ...

Ok now I have some more info. I needed other parts then the bat54s because their not through hole types of diodes so was looking which I needed for replacing those parts. Verstuurd vanaf mijn SM-G925F met Tapatalk Don´t worry, you can replace the bat54s (that as you say are SMD) and use 4 BAt42 ...

What I meant was which parts, like diodes and such. Verstuurd vanaf mijn SM-G925F met Tapatalk Yes, As I said, you have all the information in bbqkees Github webpage. https://github.com/bbqkees/Nefit-Buderus-EMS-bus-Arduino-Domoticz/tree/master/Documentation This diagram is broken in two circuits ...

Hi. I'm interested in this because I also have a nefit. What will I need to readout mine? I have several arduinos or a raspberry pi running domoticz. Preferably I bring the signal direct to my pi. What will I be needing for this(hardware)? Verstuurd vanaf mijn SM-G925F met Tapatalk You have all the ...
